Great-sounding music is made easy with a Chromecast Audio. And you'll save a fistful of dollars, too.

If you're thinking about setting up a whole-house (or even just a single-room) streaming audio solution, Sonos systems are pretty much what you'll find recommended by folks on the internet. They are easy to set up and the Sonos service offers a decent choice of streaming content providers. But the price tag - you'll be spending hundreds per room for individual Sonos amps or speakers - can be tough to swallow. We've got a solution: Use a Chromecast Audio and a few standard components and save a whole lot of money.

Three things make the Chromecast Audio a good (or even better) alternative - the Chromecast has its own 96KHz / 24bit capable audio hardware, the 3.5 mm combination output supports optical as well as analog connections, and the Google Cast app lets you create groups or zones so you can stream your music to specific sources just like you can with a Sonos. There is even a high dynamic range setting for hi-res music files. And you won't have to hack or mess around with any hardware, either. Plug your Chromecast Audio into a set of powered speakers, or a small amp and passive speakers, or even an A/V receiver, and cast some music.

Getting started

You'll need three things - a Chromecast Audio, something to play the music that's streaming and something to initiate it. The Chromecast Audio is the easy part - you'll find one them for sale at Google as well as plenty of other online retailers or on the shelf at Walmart or Best Buy. One will set you back about $35 unless you find it on sale.

To tell the Chromecast what to play, you'll need an Android or iOS device or a computer running Google Chrome (a Chromebook works really well, too). Install the Google Home app and it will walk you through finding your Chromecast(s) and setting them up. You'll then be able to stream from popular online services like Google Play Music, Pandora, Spotify and plenty of others. You can also stream your own hi-res music from a network-attached storage device using a server like Plex or an app like BubbleUPnP for your Android phone. Or you can mirror local files from your Android phone or tablet or cast audio directly from a Chrome tab across your local network. There are plenty of options when it comes to the source of your music, and more apps are adding Google Cast support all the time.

The Chromecast Audio is designed to be plug and play with other equipment.

Playing back the sound is really the only part you'll need to think about. You need a way to get the audio from the Chromecast's 3.5 mm jack to a pair of speakers (either powered or via an external amp). There is nothing special about how this is done. In fact, you can plug a pair of headphones into your Chromecast Audio and it plays exactly as you would expect. That means you can let your needs and your budget decide what you use here.

Adding some speakers

Probably the best solution would be to use a small bookshelf amplifier and a pair of passive speakers. The amp can cost as little as $20 and still deliver great sound because we're not necessarily looking for bells and whistles - we just need a way to increase the power of the signal and pass it along to some speakers. Decent bookshelf speakers start at $50 or so, while great ones can be bought for about $100. You can even splurge and use a pair of studio monitors (along with an amp capable of driving them) for one or more rooms if you plan on streaming a lot of hi-res music. The folks where you buy your speakers will be able to help you if you're not sure what to buy, Just tell them what you're planning to do and they'll point you towards everything you would need. Add in a few cables and you've just built a great audio streaming setup without breaking the bank.

Here's an example of a good setup that would compare to a pair of Sonos Play 3 speakers or a Sonos Connect amp setup:

  • A Chromecast Audio. These are around $35 and you'll get the device itself, a 3.5mm patch cable, a power supply and power cord. Keep an eye out for sales here if you are thinking about doing more than one room!

  • A bookshelf amp or car amp with a power supply. There are hundreds to choose from at every price point. I've found the SMSL SA50 to be the very best bang for your buck at around $70, but there are several like the Lepy LP-2020A that only cost about $25 and will work great, too. Be sure the amp you buy can drive your speakers. If you're not sure about any of this, drop a link and a question in the comments and the resident audiophiles will be helpful.

  • Speakers. The speakers you buy need to be able to fill up your space with sound. How big and what wattage you need depends on where you're putting them. In general, I love Pioneer's SP-BS22-LR Andrew Jones Bookshelf Loudspeakers. They're about $100 and any decent 50-watt amp will drive them well. There are countless models of bookshelf speakers from every name out there if these are a little too large (they're 7 x 13 x 9 inches in size) so you'll have plenty of options. Just be sure the speakers you buy are a good match with your amp.

You can also buy active (self-powered) speakers instead of buying a separate amp and passive speakers. Powered speakers will plug into the wall and have their own internal power supply so don't try to use a set of them with a separate amp unless you know what you're doing! The Edifier R1280T speakers look great and sound really nice for $100, but you'll also find plenty of other options. Just be sure to use active speakers without an amp - plug your Chromecast right into the input.

Even after adding in the cost of a few cables and things like speaker stands if you want or need them, this is a much cheaper alternative that sounds great and has support for more services than a Sonos system. The only downside is wiring things up, which should take just a few minutes because everything on this list will be plug and play. Now multiply the savings by the number of places you want to bring your music to, and you'll have saved a lot of money.

A great-sounding system is easy to build, or you can plug a Chromecast Audio into your existing setup.

A Chromecast Audio is also really easy to drop into your existing home stereo or entertainment center. If you already have a great setup and would love to use Google Play Music or listen to your music across your own network, all you need to do is plug a Chromecast Audio into an open optical input using a Toslink cable and fire up the Google Cast app. Being versatile is a big plus, and a Chromecast Audio will fit most anywhere and connect to anything using standard cables.

Whether you're just looking for a cheap and easy way to build a streaming stereo for one room or want to connect your whole house with multiple setups indoors or out, a Chromecast Audio is a great way to do it.
